Question

I have three equations like the following ones:

• x + y + z = 100;
• x + y – z = 50;
• x – y – z = 10;

How can I find the values of x, y, and z with Java?

String equation1="x+y+z=100;";
String equation2="x+y-z=50;";
String equation3="x-y-z=10;";

int[] SolveEquations(equation1,equation2,equation3) {
   // to do
   // how to do?    
} 

Do you have any possible solutions or other common frameworks?

Answer 1

You can use determinant to calculate values of x y and z.
Logic can be found out here http://www.intmath.com/Matrices-determinants/1_Determinants.php

And then you need to implement it in java using 3 dimensional arrays.
